One small additional piece of advise.Never change/setup your housing under duress.If you have to do it in a hurry, that is when failures occur.Plan ahead and get set up when you have lots of time to do it carefully. As above, pretty soon it becomes second nature.

Hi all,One more thing I would ask you to advice - when you finish your dive and going back to boat do you put some protective cap on your dome ,or do it when already on boat, or first wash it and clean and then when it's already not wet then put it on?
